[i]Planet of the Titans
Proposed by/Year: Paramount, 1977
What it was: The original first Star Trek movie. This one featured the crew of the original Enterprise after their five-year mission as they battle the Klingons (with the Klingon leader written to be played by legendary Japanese actor Toshiro Mifune) for a planet that’s believed to be the homeworld of an extinct race called the Titans. After falling into a black hole, the Enterprise crew has to face off against a new race, The Cygnans, who supposedly killed off the Titans. After the Enterprise ends up going back in time again to defeat the Cygnans, they end up giving fire to primitive humans and realize they (gasp!) were the Titans all along!
Why it never happened: Paramount didn’t like it. While a revised screenplay was being written when they pulled the plug, it never made it to final script form. Paramount then decided to go with a new TV series for a proposed Paramount TV network.[/i]
I had no idea about this. Frakkin Toshiro Mifune!! I so want to see this movie. Stoopid Paramount.
